8-Well Strip Frames, 12-Strip Positions — HIPS, Black, SBS Footprint | Caplugs® Evergreen (290-8103-Z1N)
These reusable High Impact Polystyrene (HIPS) 8-well strip frames hold 12 individual 8-well strips (0.2 mL PCR or ELISA format) to create a full 96-position SBS/ANSI microplate footprint, supplied non-sterile in 12/Bag packaging. Black HIPS construction minimizes optical cross-talk in fluorescence strip assays while providing autoclave compatibility (121°C / 15 psi) that standard polystyrene strip frames cannot match. The SBS-compliant footprint makes fully loaded frames compatible with standard plate washers, readers, and robotic liquid handlers without additional adapters.

Applications
- Modular ELISA: Load only the strips required for a given run and return unused antibody-coated strips to cold storage, reducing per-sample reagent waste on partial-plate programs
- Strip-based PCR: Converts 0.2 mL 8-well PCR strip tubes to an SBS plate format accepted by plate handlers and thermal cyclers with SBS-footprint blocks
- Immunoassay and antibody screening: Seats standard antibody-coated ELISA strips for use with automated plate washers and readers
- Multi-assay batching: Different strip types can be loaded in a single frame, supporting mixed-assay runs in hybridoma screening and antibody development workflows
- Automated liquid handling: HIPS rigidity withstands robotic plate gripper arms without frame fracture, making these frames suitable for high-throughput screening environments
- Cell-based strip assays: Autoclave compatibility between strip changes supports contamination-sensitive applications where standard PS frames are not adequate

Quality & Procurement
Made in USA, these Caplugs® Evergreen strip frames are manufactured from BPA-free, phthalate-free High Impact Polystyrene under ISO quality management. The rubber-toughened HIPS matrix provides the impact resistance and autoclave capability that distinguish these frames from commodity polystyrene alternatives — a meaningful advantage in automated and contamination-sensitive environments. LabSupplies.com is an authorized Caplugs® Evergreen dealer stocking part number 290-8103-Z1N and shipping from USA inventory, with volume and institutional pricing available for labs running dedicated frame-per-assay workflows.
Frequently Asked Questions
Can these strip frames be autoclaved between uses?
Yes — the High Impact Polystyrene (HIPS) construction is autoclave compatible at 121°C / 15 psi, allowing sterilization between strip changes. Standard polystyrene strip frames typically cannot withstand autoclave conditions, so HIPS is the preferred material for contamination-sensitive cell-based and immunoassay applications.
What types of strips fit in this frame?
The frame accepts standard 8-well strips, including 0.2 mL PCR strip tubes and ELISA/immunoassay strips. When 12 strips are loaded, the assembly conforms to the SBS/ANSI standard 96-well microplate footprint for use with plate washers, readers, and robotic liquid handlers.
Why is the frame black rather than clear or white?
The black color serves an optical function: it minimizes well-to-well fluorescence cross-talk in fluorescence-based strip assays, where light bleed from adjacent wells can inflate background signal. Labs running colorimetric ELISA only may use either color, but black is the preferred choice when fluorescence detection is involved.
Are the frames supplied sterile?
No — these frames are supplied non-sterile in 12/Bag packaging. For applications requiring a sterile frame, autoclaving at 121°C / 15 psi is supported, and UV decontamination is also compatible with HIPS.
